Electrical Installation and Planning
This section outlines the basics of the power wiring for the Integrated EC Titanium Motor and Drive. Sample digital and
analog control wiring diagrams are shown later in this guide.
4.1 Motor Connections
The following warnings cover considerations when using a permanent magnet motor over an induction motor.
Please review these warnings carefully before operating the permanent magnet motor.
Warning: Motor circuit may have high voltage present whenever AC power is applied, even when motor is not
rotating. Electrical shock can cause serious or fatal injury.
Warning: ECM permanent magnet motors can induce voltage and current in the motor leads by rotating the
motor shaft. Electrical shock can cause serious or fatal injury. Therefore, do not couple the load to the
motor shaft until all motor connections have been made. During any maintenance inspections, be sure
the motor shaft will not rotate.

Fuse or MCB
Fuses or MCB & cable sizes:
- check drive rating information
Control Terminals:
Based on default setting out of the box -
1. Connect a START/STOP switch to Terminal 1 or 2
Close the contact START (enable) the drive
Open the contact STOP (disable) the drive
2. Connect a 10k potentiometer on terminals 5, 6, & 7
to vary the speed from 0 to 60Hz (50Hz for kW drives)
Stop - Run 10k
